that avhile this `einhmlinient is shown and i rions journal boxes, as indicated at 5. A worm 6 is also mounted on the shaft 4 in fixed relation therewith and meshes with a worm'wheel 8 which in turn is secured to a cam shaft 9. This cam shaft carries a num ber of cams which in turn coact with respective cam levers to aetuate certain of the mechanisms, as. will be hereinafter set forth in detail. The shaft 4 which carries the driving .pulley 3 and the worm 6 carries also, at one end, a pinion 10 which meshes with a.large gear 11 (shown in Figs. 1 and 6'of the drawlngs). This gear 11 is loosely mounted for rotation on a hollow hub member 12 (Fig. 5i) arranged in an upstandingl 15 is provided upon the rear reduced end f of the hub member 12 abutting a shoulder 16, and said collar coperates with said flange to hold the hub in correct longitudinal relation Vto the upstanding portion 13. The hub is further provided with a longitudinal cylindrical bore 17 within which is supported a carrier 18, the same being splined at 19, thereby permitting lengthwise movement therein while preventing relative rotary movement. The large gear 11, which is loosely vmounted on the h'ub member 12, has a hub portion 21 on which is mounted a smaller gear 22, the latter being held against angular displacement with the former by means of a key 23, or in some other suitable manner. Disposed in the upstanding portion 13 of the body 1', at points equi-distant from the axis of said carrier, are a number of short rotatable shafts 24. llach shaft carries in fixed relation therewith a pinion 25 at the rear of the upstanding portion or upright 13, and these pinions are adapted, res]v)ectively, to mesh with the common small gear 22. i

lt will be obvious that motion imparted to the driving shaft 4 through the driving pulley 3 rotates the worm (i and the pinion 10 which is fixed on the end of said driving shaft. The worm (i in turn drives the worm wheel 8, causing rotation ofthe cam shaft E), and the pinion 10 meshing with the large gear 11. causes rotation of the latter on the hollow hub member 12, which, acting through the smaller gear 22, causes simultaneous rotation of the short shafts 24 mounted inthe upright 13. These shafts are provided with eccentric mechanism connecting with reciprocatory planers, as will be hereinafter fully described.

Taking up now in det-ail a description of tlu various functional mechanisms as nearly as possible in the order of their operation:

'lhe means for selecting and supplying nut-blanks comprises a hopper 2G mounted on a bracket 27, which in turn is suitably secured to the body 1 of the mafhne. This hopper is provided with bearings 2S for a shaft 29, .on one end of which is fixed a pulley 30 and which carries fixed thereto a pair of rotary plates 31, These plates4 are spaced apart sufficiently to accommodate a nut-blank, if the same be introduced by the dimension of vits thickness. Extending beyond these plates near-the outer circumference thereof is an annular arrangement 0f pins 33, each pin having a shank portion 34 and a conical head portion 35 enlarging from said shank portion toward the rotary plate 31. Extending adjacent the outer.cir cumference of this annular arrangement of pins for a certain distance is a curved plate. 37 which is supported in fixed relation with the hopper 26 and terminates opposite a chute member 38. The extreme outer eircumferential portion of each of the rotary plates 31 and'32 rides between the plate 37 and side walls 39 of the hopper. Collars are* provided, as indicated at 40 and 41, on the shaft 29 to restrict longitudinal movement of said shaft in the hopper and hold the rotaryplates in their proper positions. Referring to Fig. 15 of the drawings, it will be seen that the rotary plate 32 is provided with indentations 42 extending to'wardthe inner wall of the rotary plate 31. The transverse distance between the pins 33 is sufficient to permit of the passage of a nut-blank therethrough in the dimension of its width. The conical head portions, however, on these pins foreshorten the distance to an extent suilicient to prevent passage therethrough of a nut-blank in thedimension of its width opposite these conical head portions. The nut-blanks used in this particular embodiment of the invention are hexagonal and are preferably` crowned to give them a finished appearance. The machine calculates an operation on the crowned face of each nut, and accordingly it is desirable to present the nuts with their crown faces in position to be operated upon-by the planing mechanism which will be hereinafter described. The nut-blanks fall by gravity from the hopper in between the rotary plates, which are constantly rotated by means of the shaft 29, heilig driven through the medium of the pulley 30, the belt 44 and a lower pulley 45,

which in turn is driven from the main driving shaft, and are not permltted to pass between adjacent pins 33, unless said nuts are presented with their crown facesvagainst4 the rotary plate 31.l If, however, the crown faces are presented against the rotary plate 31 the crowning sufficiently relieves the nuts at points opposite the conical head portions of the pins to permit the ,same

to pass therebetween. The plates in their rotary movement may then advance the nut y the` cl'nite rectioii oil feed.

feeding takes place at a time in the operation of the machine when certain parts of the holding mechanism or magazine have been moved rearwardly toward the chute 3S (see Fig. 47). It willbe obvious, therefore,

that in certain embodiments of the inven-` tion the feeding'inay be of a yielding na`` ture, and thataccoi'dingly il. the machine should become .choked by reason `of the nuts not being properly disixharged, or for any other reason, the `feed plunger iv-ill yield' preventing further forward movement of `against the action of the spring (it,` thereby" the blanks relative to `the .holding means and vobviating the possibility of breakage of the parts.

The holding mechamiam-The holding mechanism comprises essentially.J in this em.-

mitsl the passage of a nut-blank therethrough `without occasioning substantial pressure on Said blank.' This chuck is split toforin gripperjaws 67 and comprises a The interior of responding to tl'iose of the chuck and 'coincid'ing With the interior walls thereof. yThis magazine' member has a flange portion 72 to' Ward the rear thereof, the inner or front side of which is adapted to abut al projecting cylindrical hub portion .T3 extending rearwardly from the carrier 18. The maga' zine member 7() is keyed to said rearwardly extending cylindrical hub portionA 73 ,and A :flanged clamping mei'iiber 741y isadalfited to 'be threaded over said rearwardly projecting hiib portion 7 to confine the flanged por# tion 72 ofthe magazine member to hold the latter against relative longitinlinal" move` rnient with the carrier i8.

The sleeve 75 is slotted at 80 to accom inodate the inner ends 81 of arms S2 of the bell crank levers and to thc rear of these slots there is provided a {iai-cd fiange portion 83 within which is secured a ring 84. projecting rearwardly some distance beyond the end of said flange. A coaxial recess is provided extending rearwardly into the projecting hub portion' T23 of the carrier 18, and within this rccessa contractile spring SG is disposed adapted nor- 79. The rearward movement of the sleeve 75.is limited by an adjustable threaded tension member 90 which is disposed in the forward end of the carrier, interiorly recessed, as indicated at 91, and provided with an inner conical face 92 adapted to engage with an outer conical face 93 formel on the sleeve. It will be obvious, therefore, that the liu member 12 is held against rotary movement in the upright portion of the bodyvl by means of the'key 111; that the carrier'lf is held against rotary movement in said first member by means of the spline or feather 19; that the magazine member 70 is held against rotary movement by means of a key, and that the sleeve is held against rotary movement by means of the'engagement of the lower ends of the arms of the bell crank levers engaging with the slots in said sleeve member. It will be equally obvious that the carrier is adapted to have a longitudinal movement relative to the upright portion 13 of the body 1 of the machine, that as this carrier moves longitudinally the sleeve and the magazinemembers' are carried therewith, and that the sleeve member has a longitudinal,movement between the magazine and the carrier. Projecting rearwardly and downwardly from the carrier 18 is a bifurcated bracket member 94 (Fig. 9) having arms 95 adapted to straddle a double bell 4crank lever- 96 (Fig. S) 'and serve as a fulcrum therefor. This hell crank lever has apair of upwardlyextending arins 97 provided on their inner sides with bint-ks 9S which are adapted to project into the annular groove 99 "formed in the ring member 87.' This bell crank lever is also` provided with forwardly eX- tending arms 100 adapted to straddle a yoke member 101 which carries a slidablel `block 102 therein.

A bolt 103 'is passed from one of the arms 100- to the other through the block 102 serving to provide a connection between the bell crank lever and an actuating lever 104. This actuating lever is fulcrunied at 105 in a bracket 10G arranged on the body 1 and is provided on the opposite side of said V'fulcrum with a cam roll 107 which coacts with an actuating cam 1.08 secured to the main cam shaft 9. The carrier 18 is provided with veitifal ways 109 on opposite sides thereof and is suitably yconnected through the blocks 110 and the levers 112 to a rock shaft 113 journaled in the body of the machine. Disposed between the levers 112, extending rear wardly and fixedto said rock shaft 113, is a cam roll carrying lever 111 provided with a cam roll 115 adapted to coact with the face lcam 11G. This face cam actuates the carrier 18 through the mechanism just de? scribed to cause longitudinal movement of said carrier. Accordingly it will be seen.

,that as the eed plunger, heretofore de! scribed, is retracted to permit a nut-blank to enter ythe bottom of the chute 38, it is desirable to actuate the carrier to carry the rear end of the magazine member back a Uainst or adjacent the opening in the chute. The feed plunger may then be advanced to pass the lowermost iiut-blank of the chute from its position therein into the rear end of the magazine which will be at that time adjacent the chute.

It will be apparent that the magazine employed in this preferred embodiment accommodates a large number of nut-blanks at one time, and that the feed of the nutblaiiks through the magazine is by successive nut-blanks urging those preceding along toward the gripper member. 1n start ingthe machine this magazine may be filled by hand, or suflicient time may be allowed to elapse to permit the same to be filled automatically. The cam 108, which operates to throw the ring member 3'? in and out of engagement with the bell` crank levers 78, is so timed that, as the feed plunger 49 is moving forwardly to urge a nut-blank into the magazine, the ring member is withdrawn from engagement with said bell crank levers to permit the spring 8G to urge the sleeve member forwardly, disengaging the conical` faces of the sleeve member and the clutch, respectively, and permitting the gripper members to assunil their normal ungriliiping position. Substantially at the end of the period offeed of the nut-blank the ring member is thrown into engagement with the bell crank levers to cause engagement of the said conical faces and bring about a pressure on the side alls of the nut-blank which at that time is partially' opposite the gripper jaws to hold lthe same securely against longitudinal or angular displacement.

causing an exact registration ofthe nutblank with the gripper member, whereby aportion of said nut-blank said gripper member and is adapted to be exposed to the action of the planers. At this time the carrier has been moved longitudinally to a' rearward position by the action of the cani 111i, and at substantially this time the 'am 108 operates to cause` movement Aof the sleeve n'ieinber longitudinally, causing a gripping action of the gripper jaws on the nut-blank. The cari'ier or slide is then advanced carrying the sleeve member, themaganine, the gripper jaws and the niitblank tightly gripped by the latter. There then begins a. series of progressive planerpositioning movements or advancements transversely of the cutting plane caused by the cam 116, whereby the carrier is slightly advanced at every reciprocation of the planers at the. same time preserving the sinne angular relation with respect to the cutting planes, thereby producing a slot or a plu rality of slots which have been cut in easy stages and thereby progressively enlarged.

It will be noted Kthat the cani path of the cani 11G is also provided with retreats after each advance. The purpose of these is to cause a Aslight'retreat of the carrier after cach cil-tting in order to permit the planes to return to initial position relieved of their strict engagement with the nut. vAs the cani-shaft nears the end of its revolution and the cutting is finished, the stop 11S advances as the carrier retreats and the feed plunger operates to urge another nut fi'oiii the chute into. theniagazinc.
